I feed once a week a rat pup about the width of their widest part. It leaves a slight barely noticeable lump in their body. I feel like they could take more because they're still hunting after just one, also they are June 2013 babies in the upper 200 gram range with a good length to them I'd say at least 2.5 feet. Breeder said he grew them slowly since he had no plans to breed them. What do you think?
